How to charge capacitors

  1. Aug 30, 2011 #1
    I know that in order to charge a capacitor, you must have a power source voltage greater than or equal to the desired voltage in the capacitor. Knowing this, is there any way to achieve a higher voltage DC(from a lower voltage DC) without using a step-up transformer?

    Look up charge pumps.

    I need to use batteries, so AC is out of the question.

    Thanks. That's pretty much what I need. Now all I have to do is figure out wiki..... So basically a charge pump is a device that charges capacitors in parallel and discharges in a series?

    Right.
